eBay question

I bought some tickets, well tried to using buy now. Emailed seller straight away, heard not a thing for nigh on 2 months and they emailed me today saying i need to pay now they have the tix. I bought some elsewhere assuming it had all fallen through. I don't actually need that account any more anyway but not sure best approach - ignore, respond ??

Respond I guess. Let them know the deal is off and he left it too late to get back to you. Two months with no come back from the vendor is a more than reasonable amount of time to assume he won't trade.
